In a recent article in BBC.com I saw the above map of global Cancer cases. Looks a lot like a map of global GDP ! Look how Kenya is higher than its neighbors as is South Africa. See South Korea or tiny Singapore ? Israel is higher than its neighbors and Egypt higher than most of its !
My theory is : the more developed an economy, the more people are eating processed foods, or foods from a box. In poor countries people eat natural food, they cannot afford food which comes in a box, or fast food, or microwaves.
So my advice to you : eat natural foods. Avoid eating things that come in a box or a can. Avoid fast food. The cheapest food for lunch is not a good choice ! 
Similarly for my diabetic friends : eat natural and unprocessed foods. It will go a long way in helping you. The diabetics are usually the rich too!

Many times when I talk to my parents and say "Eat an Apple" they say "Oh it has sugar in it.". That is not the right thing to look at as all sugar is not the same. Did you know that ?

In general, for better health you should not eat processed foods which basically means anything that comes out of a factory. You should eat whole, natural foods. They are better for you.
The same goes for sugar. Modern table sugar is extremely extremely processed, often added into furthermore processed foods such as baked goods.
Here is a link to wikipedia where you can see how it is made, but a few quotes are : 
heated to kill enzymes, resulting supersaturated solution is seeded, cane sugar requires further processing to provide the free-flowing white table sugar required by the consumer, phosphatation process, an ion-exchange resin ....
sounds natural ?
How can we compare that to the sugar in an apple ?

If you like sweet in your coffee or tea, try Palm Jaggery, which is palm tree sap, boiled and hardened, a lot less processed than table sugar. I actually like the taste in tea as well.
Also, you need to be aware that fructose(fruit sugar) is different than sucrose (table sugar). 


Next time some says avoid sugar please realize everything you eat will turn to glucose in your body. What you should not do is cut out natural sources of vitamins and minerals which include all fruits and vegetables. That will not be good for your health.
